A proto-spiderweb in space

Astronomers studying a cluster of still-forming protogalaxies seen as they were more than 10 billion years ago have found that a giant galaxy in the center of the cluster is forming from a surprisingly-dense soup…


Tentacles in space

New observations from the NASA/ESA Hubble Space Telescope have revealed the intricate structure of the galaxy NGC 4696 in greater detail than ever before. The elliptical galaxy is a beautiful cosmic oddity with a bright…


Finding a new galactic neighbor

An international team led by researchers from Tohoku University has found an extremely faint dwarf satellite galaxy of the Milky Way. The team’s discovery is part of the ongoing Subaru Strategic Survey using Hyper Suprime-Cam….


Count again

Astronomers using data from the NASA/ESA Hubble Space Telescopes and other telescopes have performed an accurate census of the number of galaxies in the Universe. The group came to the surprising conclusion that there are…


The Dark Wanderer

Astronomers have used NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton X-ray observatory to discover an extremely luminous, variable X-ray source located outside the center of its parent galaxy. This peculiar object could be a wandering…


Pandora’s Magnifying Glass

In the ongoing hunt for the universe’s earliest galaxies, NASA’s Spitzer Space Telescope has wrapped up its observations for the Frontier Fields project. This ambitious project has combined the power of all three of NASA’s…


Starbridge in space

This image captured by the Subaru Telescope shows a “brook of stars” flowing through a galaxy. This stream of stars is actually the result of the dwarf galaxy NGC 4449 (lower left) devouring another nearby…
